What does the Voice calculator calculate?

The calculator allows you to compare different tariffs and choose the most beneficial option according to your needs. The calculator shows total monthly costs, breakdown by service types (calls, SMS, internet), and comparison between different tariffs. The calculator is useful for anyone who wants to optimize their costs for mobile and internet services, for people planning to switch operators or tariffs, and for everyone who wants to compare different options before choosing a new service. It helps you make informed decisions and reduce your telecommunications costs.

Example with specific numbers
Example: Tariff comparison - 300 min calls, 100 SMS, 5 GB internet
- Monthly usage:
- Calls: 300 minutes
- SMS: 100 messages
- Internet: 5 GB
- Tariff A: Base 20 BGN + additional services = ~35 BGN/month
- Tariff B: Everyday tariff 25 BGN = ~30 BGN/month
- Tariff C: Unlimited tariff 40 BGN = 40 BGN/month
- Most beneficial: Tariff B (30 BGN/month)
For usage of 300 minutes calls, 100 SMS, and 5 GB internet, Tariff B is most beneficial at 30 BGN/month. Tariff A requires additional payments and costs 35 BGN, while unlimited Tariff C is expensive (40 BGN) for this usage. The comparison helps you choose the optimal tariff according to your needs.
